Abstract
The utility model discloses a radio frequency cable, which comprises a core, a foaming insulation layer, a shielding layer and a PVC sheath. The foaming insulation layer, the shielding layer and the PVC sheath are orderly sheathed on the outer surface of the core. The core is a copper-clad aluminum tube. According to the technical scheme of the utility model, the copper-clad aluminum tube is adopted instead of a pure copper tube. Thus, the cost is lower and the energy consumption is small.
Description
Technical field
The utility model relates generally to the telecommunication cable technical field.
Background technology
Radio frequency cable has widely and uses as the communications line.The core of common radio frequency cable adopts solid conductor or copper tube in the market, and cost is high, and power consumption is large.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this utility model has provided the lower radio frequency cable of a kind of cost.
Technical scheme: for achieving the above object, the utility model by the following technical solutions: a kind of radio frequency cable, comprise core, and the foaming insulation layer, screen and the PVC sheath that are enclosed within successively core outer surface, wherein said core is copper cladding aluminium pipe.
As preferably, described screen is the copper strips that twists in the insulating barrier outer surface.
As preferably, the copper layer thickness that the unlined aluminium tube outside coats in the described copper cladding aluminium pipe is 0.01～0.1mm.
Beneficial effect: compared with prior art, the utlity model has following advantage: utilize copper cladding aluminium pipe to replace pure copper tube, cost is lower, and energy consumption is little.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, core 1, insulating barrier 2, screen 3, PVC sheath 4.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of radio frequency cable, it comprises core, and the foaming insulation layer, screen and the PVC sheath that are enclosed within successively core outer surface, its SMIS has adopted copper cladding aluminium pipe, this copper cladding aluminium pipe is that copper strips is coated on the aluminum pipe that diameter is 8～14mm, and is then stretched and form the Copper Foil of 0.01～0.1mm.Owing to normally used pure copper tube replaced with copper cladding aluminium pipe, thereby reduced cost, having reduced simultaneously energy consumption.
